What is stem cell research?

Question

explain it in brief detail please

Answer 1

There are two types of stem cells - the study of these cells it is stem cell reasearch - Sorry this isn't brief................

Embryonic stem cells
The best and most readily understood example of a stem cell is that of the fertilized egg, or zygote. A zygote is a single cell that is formed by the union of a sperm and ovum. Once that single cell or zygote starts dividing, it is known as an embryo. One cell becomes two, two become four, four become eight, eight to sixteen, and so on, doubling rapidly until it ultimately creates the entire sophisticated organism reading this article - meaning you. That organism, a person, is an immensely complicated structure consisting of many, many billions of cells with functions as diverse as those of your eyes, your heart, your immune system, the color of your skin, your brain, etc.
During the early stages of embryonic development, if one takes cells from an embryo consisting of fewer than 1000 cells and then transfers some of these cells into a Petri dish, they can be grown indefinitely. These cells are known as "embryonic stem cells."

Adult Stem cells, or committed stem cells. The adult stem cell is one of the class of cells that we have been able to manipulate quite effectively in the bone marrow transplant arena over the past 30 years. These are stem cells that are tissue specific. Rather than typically giving rise to all of the cells of the body, these cells are capable of giving rise only to the cells of a specific tissue or organ.

The best characterized example of an adult stem cell is the blood stem cell (the hematopoietic stem cell). When we refer to a bone marrow transplant, a stem cell transplant, or a blood transplant, the cell being transplanted is the hematopoietic stem cell, or blood stem cell. This cell is a very rare cell that is found primarily within the bone marrow of the adult.

One of the exciting discoveries of the last couple of years has been the overturning of a long-held scientific belief that an adult stem cell was a completely committed stem cell. We used to believe that a hematopoietic, or blood-forming stem cell, could only create other blood cells and could never become another type of stem cell. That belief is probably incorrect. There is now evidence that some of these apparently committed adult stem cells may be able to change direction to become a stem cell in a different organ.

Answer 2

In undeveloped or underdeveloped fetuses, there are cells that have not specialized yet. i.e. skin, bone, liver, muscle, etc. Stem cell research is a very promising field of study that could literally replace any part of the human body with a copy of the original. Imagine an organ transplant where you don't have to take anti-rejection drugs for the rest of your life. Imagine eliminating leukemia with one transfusion. Instead, the right and left wings of govt are content to argue about it forever without moving forward.

Answer 3

synthetic body parts....very profitable sold to those who want to try and live forever !
